1N4752A TR PBFREE

Overview

The Central Semiconductor Corp 1N4752A TR PBFREE is a silicon Zener diode designed for voltage regulation. It features a nominal Zener voltage of 33 V with a 5% tolerance, tested at a current of 7.5 mA. The device dissipates up to 1.0 W of power and operates within a temperature range of -65 °C to +200 °C. It utilizes the DO-41 axial through-hole package and includes a maximum reverse leakage current of 5.0 µA.

Feature Summary

• Provides stable voltage regulation using silicon Zener technology
• Features hermetically sealed glass construction for corrosion resistance
• Supports high-temperature operation suitable for industrial environments

Applications

• Industrial circuit voltage regulation
• Commercial equipment power supplies
• Computer system protection circuits

Procurement Notes

Verify that the ordering suffix 'TR' corresponds to the specific reel packaging configuration required for your assembly line. Confirm the 'PBFREE' designation aligns with RoHS compliance requirements for your manufacturing process. Ensure the DO-41 through-hole footprint matches your PCB layout specifications before finalizing procurement.

Selection Notes

Select this component when a precise 33 V reference is needed in a standard axial package. The 1.0 W power rating allows for robust performance in moderate current applications. Verify that the operating environment stays within the specified -65 °C to +200 °C junction temperature limits to ensure long-term reliability and consistent electrical characteristics.
